KaaTon is a rare Runeword created by combining a Kaa Rune of Ritual and a Ton Rune of Invocation.
How to Create KaaTon
You can create KaaTon by adding the rare Kaa Rune of Ritual and the magic Ton Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Kaa - Lose 1% of your Maximum Life. (2)
Ton - Evoke the Sorcerer's ites, dealing damage to enemies. (25)
Meteor
Overflow
When KaaTon overflows, you receive the Ton Rune's overflow effect (Increased Meteorites Spawned) 0.04 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
